Re: unsure what to think/do
This could be teething, could be an ear infection, or could just be a little quirk your baby has picked up. As long as he continues to wet enough diapers, and doesn't seem sick, I wouldn't worry. I'd just treat this with patience, and hope that it eventually goes away. It might not hurt to take your LO in to the pediatrician, though, and have someone take a peek at his ears.
